Title: Steering control method for unmanned work vehicle
Inventor: YAMAMOTO SHIGEHIRO
IPC: B65F3/00
Filed: 1993-06-15
Abstract: PURPOSE:To always drive an unmanned work vehicle with desired distances secured to the right and left obstacles of the vehicle by setting the offset value used for the steering amount based on the feedback value due to the deviation of the value detected by a sensor from the relevant traveling course. CONSTITUTION:The unmanned work vehicle 1 calculates its position on a traveling course and then calculates the feedback value of signals to perform the steering control in accordance with the calculated position of the vehicle. Then, the vehicle 1 compares the detected distance (d) between the vehicle and an obstacle 2 with the desired space value D and then calculates the offset value of the feedback value based on the result of comparison. Then, the vehicle 1 calculates a steered variable from the feedback value acquired by the hitherto calculations and the offset value. Then, the steering control of the vehicle 1 is carried out. Thus, it is possible to set a steering amount to secure the space D when the deviation of the vehicle 1 from a prescribed traveling course (x axis) is generated in an optional form. Therefore, a stable distance D is kept in particular to an obstacle in a oblique direction.

Abstract: PURPOSE:To improve withstand voltage of a cathode-ray tube by making the angle in the vacuum side between the surface of a connected part of third grid, which composes an electron gun, with bead glass and the surface of the bead glass >=90 deg.. CONSTITUTION:The angle theta in the vacuum side between the surface of the connected part of a third grid 7, which composes an electron gun, with bead glass and the surface of the bead glass is made to be >=90 deg.. In the case of the angle theta>=90 deg., the intensity of an electron field in the periphery of the connected part is moderated and electric field emitting electron generation in the connected part is suppressed and electron collision to the bead glass 9 is lessened and positive-charging of the bead glass 9 caused by secondary electron discharge is decreased. As a result, electric field distribution in the neck part becomes hard to be disordered and electric discharge along with the surface of the bead glass 9 hardly occurs. In this way, withstand voltage of the cathode-ray tube is improved.

IPC: H04B5/02
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To make graspable whether an information storage medium exists within the area where the information storage medium receives power supply to be operable, in a data communication equipment which performs data communication while feeding power to the external information storage medium having a communication function in a non-contact manner. SOLUTION: In this data communication equipment, when a receiving antenna receives radio waves from an information storage medium, a signal processing part detects and binarizes the radio waves and outputs the waves as a pulse signal. When the pulse is outputted from the signal processing part, whether pulses are further outputted is judged in a preset pulse judging period, and when pulses are outputted during the pulse judging period, the outputted pulses are judged as being based on a transmitted output from an IC card. According to such a configuration, it is possible to grasp whether the IC card exists within its operable area even in situation in which data are difficult to be normally received.
